Preliminary study of movements of harbor porpoises ( Phocoena phocoena ) in the Bay of Fundy using radiotelemetry
Six harbor porpoises captured in herring weirs between September 1973 and September 1974 on the southern coast of New Brunswick were tagged and released. The three smallest animals were given visible dorsal fin tags, and the three larger specimens radiotelemetric packages attached to their dorsal fi...
